android 闹钟声音大小,Android闹钟音量逐渐增加

您可以自己做.没什么复杂的.

触发PendingIntent后,请使用处理程序来进行增加.

>创建将以AudioManager或应用程序上下文作为参数的类.

public class VolumeRunnable implements Runnable{

private AudioManager mAudioManager;

private Handler mHandlerThatWillIncreaseVolume;

private final static int DELAY_UNTILL_NEXT_INCREASE = 30*1000;//30 seconds between each increment

VolumeRunnable(AudioManager audioManager, Handler handler){

this.mAudioManager = audioManager;

this.mHandlerThatWillIncreaseVolume = handler;

}

@Override

public void run(){

int currentAlarmVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_ALARM);

if(currentAlarmVolume != mAudioManager.getStreamMaxVolume(AudioManager.STREAM_ALARM)){ //if we havent reached the max

//here increase the volume of the alarm stream by adding currentAlarmVolume+someNewFactor

mHandlerThatWillIncreaseVolume.postDelayed(this,DELAY_UNTILL_NEXT_INCREASE); //"recursively call this runnable again with some delay between each increment of the volume, untill the condition above is satisfied.

}

}

}

>触发PendingIntent后,调用此Runnable：

someHandler.post(new VolumeRunnable(mAudioManager, someHandler));

我希望这能给您想法.原谅任何错误或错别字.
